To aZZ'w/wfmz'mmy concern Be it known that I, WILLIAM HILDE- BRAND, a citizen of the United States, resid7 ing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal-Protected Rubber Heels, of which the following is a specification.

My invention relates to rubber heels and its object is to metal-line the outer ends ol the holes provided in thistype `ol heel to be engaged by the screws or nails by means of' which they are secured to the leather heel of the shoe. Another object is to nietal-line f the walls of the countersinks of these bores which are provided for the head of the nail or screw, so as to resist wear upon the rubber and prolong the life of the heel without the use of separate studs or plates which add to the weight, and interfere with the resiliency of the heel.

With these general objects in view my invention consists in the novel construction, combination and arrangement of parts, all

as hereinafter described in detail, illustrated of the heel, snowinglireedoni of movement in one of the fastening screws or nails.

Fig. 5 is a perspective view of one form of metal lining.

Fig. 6 is a modification of Fig. 5 and showing the metal bore lining and the usual embedded washer partly disconnected and flexibly connected.

Fig. 7 is view of the blank out of which the Fig. 6 modification isformed.

In the several views 2 represents a fragment of a shoe with a leather heel section and a rubber heel section-3 and 4, respectively. The rubber heel 4 is shown provided with the usual screw or nail holes 5, in the present illustration six in number. The outer ends of the holes 5 are enlarged to form counterbores G" foriinetal` linings en` gaged by heads 7 of screws or nails 8J `Each counterbore 6 has its walls and bottom lined "with a cylindrical steel shell"having"` abottom labeled 9 in Figs. 1 to 5 and 14 in Fig. 6,

which functions as the usual embedded rubber heel washer which prevents the head from pullingthrough the bore 5. In Figs. 1 to 5 the lining has a tapered wall 10 on which is an` edge fiange 11, and in Fig. 6 a uniformly cylindrical wall 15 with a flange 1S. The flanges provide metal contacts that resist wear upon the rubber without inaterially interfering with its resilience. When the flange is worn away the edge of the cylindrical wall will continue to function as a metal guard until the rubber is worn down .to the bottom or washer portion 9 or 14. i

The lining is made sufficiently large to indicated in Fig. 4.v The bottom or washer portion. 9 is provided with a nail or screw` `permit the lateral movement of the head 7 mits liquid or plastic rubber to flow in between the edge 1G of the linings and the bottoin or washer portion. The latter is elastically held to the wall portion 10 or 15 by a connective portion 17 which makes the washer portion partly independent of the cylindrical wall portion, at least to the extent of permitting a moderate degree of relative movement or flexibility. y

As the conventional rubber heel must have a certain number of holes 5 for fastening screws or nails, lining. these holes with metal in the manner indicated obviates many of the objections to studdings of metal and heel plates, and provides a neat means of metal-l shoeing as indicated by a glance at Fig. 2, which to all appearances is the same as the plain rubber heel. In fact the rim of metal which lines the outer ends of the holes rather enhances than detracts from the appearance 2. The combination with a rubber heel having eountersunk holes therein, of hollow vmetal'members lining the bottoms and sides of the eountersinks, Washers to be engaged 15 'b' 'niils andthe Llike :L connective ortion 17 y a P that exibly connects each of seid washers with said members and protective Vmetall rings for the sides of the ooun'rersinks.

In testimony 'whereof I have hereunto 20 signed my name.
